Pajama Pants Pattern –

It’s not very often you see my whole crew around here… but here we are! Enjoying our pj pants. I got all this flannel last Black Friday at Joann… {$0.49 a yard!!!} I stocked up and have been using it for many projects…

I’ll be out of the country this year on Black Friday, so good thing I bought a lot last year.

These three!! Seriously… I love them so much, but it is SO hard to get a decent photo.. There was a lot of laughing, and then a lot of flopping back onto the bed…

We just embraced the laying down look! Even this was tricky as the boys kept popping their heads up..

Ok! Enough photos of us, let’s get on with making YOU some fun new Pajamas!

How to make pajama pants –

Go print the free pattern by clicking the image below..

Decide your sizing… the chart is on the pattern and also here… because this is a unisex pattern the sizing is quite different than my other size charts… please just go by the hip measurement and not by age for the kids… my three kids are thin and tall so they are in a xxs, two in S… Just adjust the leg length to fit…

Printing options 

You do not have to print all the pages if just making the kids pajama pants sewing pattern…

For kids sizes print Pages  2-5, 8-11, 14-17, 20-23 for all kids and add26-28/29 only for sizes M and L Kids}

For adult sizes print all pages

If making kids and adult sizes print all pages once, then trace on tissue paper for each size

Trim the pages and assemble.. it should look like this… If you’ve only printed some pages you will just be putting the middle part together. Trace the size/s you need. Measure inseam and adjust the leg length as needed.

Fabric needs…{45″ wide flannel or other soft woven}

Kids: XXS and XS = 1 yard, S, M and L = 2.5

Adults: XS, S, M = 2 5/8 yard, L and XL = 2 3/4 yard

{If you are working with what you already have I’ll give tips for making it with less fabric below… using cuffs and a waistband you can reduce the fabric used. }

Elastic – I used 1″ wide for the kids and 1.5″ wide. for the adults. You really can use either if you have on hand.

How to sew pajama pants-

All seams are 3/8″ {1 cm} seam allowance unless otherwise noted.

Trace the pattern and cut out 2 pieces in mirror for the size required. Fold each leg in half with right sides together and sew.

Turn one leg right side out and place one inside the other. Match up the front and back center crotch seams. Sew.

If you have a serger, finish the top of the pants and each leg. If you don’t have a serger press over 1/4″ of the fabric to prepare for next step.

Fold 1″ under and hem each leg. {shorten the legs before you hem}

Fold over the waistband. If using 1″ elastic fold over 1.5″. If you pressed under the 1/4″ to prep make sure that is still turned under so you have a finished raw edge.

Sew around the waistband leaving a 2″ opening to thread the elastic.

NOTE: if you want to add pockets, scroll to the bottom for instructions and do so now before you thread the elastic.

Measure your waist and cut elastic 1″ smaller than measurement. Thread the elastic through the casing.

Overlap ends by 1/2″ and stitch. Pull the elastic back inside the casing and sew the opening closed.

Evenly distribute the gathers. Mark the center back and two side. Sew up and down on the elastic to secure in place. This will prevent twisting.

now… let’s say you want to make an adult size and you only have 2 yards of flannel.. this was me.. trying to use up my flannel stash and make my husband the side M adult pajama pants pattern. I was able to make it work with using up scraps from my sons pants and adding cuffs and a waistband to the adult size. Here’s how it will look.

I shortened the top of my pattern by 3″ and made the waistband 3.5″ tall to replace it. You can cut one long piece or two the same width as the top of the pants. The cuff height will depend on how short of fabric you are {haha}. If you are short 3″ on the bottom of the pattern you will cut the cuffs 2x that.. so my pattern was short 3″, so my cuffs are 6″ {plus seam allowance} tall and as wide as the bottom of the pants leg. Cut 2 cuffs.

Fold the cuff in half and match the raw edges with the pants bottom.

Sew and fold open. Top-stitch if you want.

Sew the sides of the waistband together if you cut 2, or just sew the ends together if you cut one long piece.

Fold the waistband in half and match raw edges with top of pants. Sew waistband to pants leaving a 2″ opening to thread elastic.

If you are adding pockets do so now with the instructions below. The thread elastic.

Measure, thread and sew the elastic as described above.

Want to add pockets? Add before you thread the elastic. You can add to any size like this… Trace your hand {or the hand of the pants owner} onto a piece of paper. Draw an oval around the hand and add the wingy part that ends in a straight line.. this is where you will sew to the pants. Cut 4 {two pairs}.

Sew the curved edge of the pocket. Lay the pants flat so the center seams are in the middle and the sides are a flat fold. On your pants measure down 2.5″ from the top and line up the pocket with the side. Cut open the side of the pants from top to bottom of pocket. 

Turn the pocket right side out and flip your pants to the inside. Place the pocket in the hole with the right side of the pocket touching the right side of the pants. {this is from the inside of the pants view} Pin in place. Sew.

This is what it looks like from the right side of the pants. Push the pock into the pants. 

Top stitch from top to bottom on front and back of the pants.
